Unskilled labor as in, I do not have any degrees or certifications that I can simply take to a new employer to leverage anything above starting at the bottom. This will almost always mean making less money. At-will employment mixed with unequal application of company rules and policy means that any day at work could be my last. Unemployment checks are a joke, and would not even cover my rent.

What would you call that?

It's really not, there's jobs out there that can be learned in a week on the job, and people who don't have any qualifications to do much else. If you're one of those, you're a special kind of fucked, because you're among the easiest people to replace.

There's trained and highly trained labor. All labor takes some degree of education and training, but some labor takes more dedication than that, such as medicine.
